Free tool · runs on your device
Repair your 3D model.
Upload an STL, OBJ, OFF or PLY file. The tool removes broken and duplicate faces, aligns faces and closes simple flat holes. Your file stays on your device.

What does the repair do?
This tool fixes common mesh problems. It does not change dimensions or solve every intersecting or missing surface. Any remaining open or non-manifold edges appear in the result. Check the file before printing.
